I finally caught up, via an 8-episodes marathon yesterday, now I've finished watching Season 4. As good as ever.
Spoiler
I was a little worried on how they're now going for "high fantasy" in the last two episodes you have these skeleton warriors, fairy sprites, a wizard inside a tree... It's exciting, but I'm worried about the budget D:
By the way, I was kind of shocked by the complete absence of Gendry this season.
